Thanks for all the comments guys. It's looking as if the .46 LA isn't a good choice for the Nexstar. I'll look into some of the other engines you guys suggested. Because I definitly don't want to be under powered in any of my planes. But I'd like to keep cost to a minimum.

I have flown a 4* 60 on a buddy box. I made a few approaches and it seemed to handle as if it were on rails. It goes where you point it. And it doesn't have the characteristics of a card board box in the air like my Nexstar. Only problem I have with the 4* is everyone at our field has one. So just to shake things up, i'm gonna try out the Super Sportster. I'm looking at getting the arf and stripping it right away of the covering. My son wants me to get a blue airplane. And I don't particularly care for the trim scheme on there. I'm thinking a Navy blue top and a bright yellow bottom. You know with some yellow trim on top too. I can't wait!

Thanks again for all the words of advice.
